Bosch Duraterm® Glow Plug Technology With a long history of diesel fuel injection expertise and innovation, Bosch leads the way in glow plug technology with its patented Duraterm® dual-control coil design. This technology utilizes a self-regulating system that reduces glow wait time by more than 50%. The patented dual control regulating and heating coil system effectively directs current draw, enabling the glow plug to reach higher temperatures more quickly for faster engine start-up. For vehicles with a post-glow* control system, this advanced technology results in a post-glow heating phase which allows for more efficient overall engine performance.

* The post glow feature allows the glow plug to remain active for up to three minutes after the vehicle has started.

Trust the experience of BoschBosch original equipment quality glow plugs are an essential part of every tune-up, and are available for domestic and import diesel cars and light trucks. Trust Bosch diesel engine parts for the ultimate in diesel engine performance.

Bosch also offers Fast Glow Kits for older European applications equipped with slow glow technology. Upgrading an older system with Duraterm® glow plug technology will improve overall performance by providing:

• Faster engine start-up for reduced waiting time

• Post-glow heating for smoother idling and reduced emissions

Bosch Glow Plugs are critical for diesel engine start-upThe pre-heat, starting and post-glow phases of a glow plug’s operation affect not only the start-up function, but the vehicle’s overall performance as well (hard or no-start engine condition, poor idling after initial start-up, and/or engine oil dilution due to excessive cranking). That’s why Bosch Glow Plugs are critical for diesel engine start-up, and supply the essential heat necessary to initiate combustion in cold weather conditions. They are designed and built to last for season after season of quick, reliable start-ups.
